One is an a la carte program of college level classes that's the traditional method for earning higher education credits for precocious high school students. The other is a two-year, well-rounded syllabus created in Switzerland and (at different points in its 40-plus year run) financed by UNESCO and the Gates Foundation, which is gaining steam. They are the Advanced Placement and International Baccalaureate programs, respectively.
According to a recent blog post over at The Washington Post, schools, such as Colorado College, are allowing scores from either of their tests to replace the SAT and ACT in college admissions. But, because of its expense and affiliation with the United Nations and liberal ideologies, the IB faces some opposition.
A website called Truth About IB opposes the program on several fronts, including its emphasis on worldliness: "IB's primary purpose is to promote globalism and turn our children into global citizens," its website reads. "TAIB'S primary purpose is to celebrate what it means to be American and to preserve freedom for our children and grandchildren."
A recent New York Times article cited similar concerns from parents:
Some parents say it is anti-American and too closely tied to both the United Nations and radical environmentalism. From its start in 1968 until 1976, the program was financed partly by Unesco. It is now associated with the United Nations Economic and Social Council, and until recently it endorsed the Earth Charter, a declaration of principles of sustainability that originated at the United Nations.“When there is a program at the school with a specific agenda, which in this case is the United Nations agenda, I have a problem with it,” said Ann Marie Banfield, who unsuccessfully opposed the adoption of the I.B. program in Bedford, N.H.
